Figure 1From: Structuring and extracting knowledge for the support of hypothesis generation in molecular biologyCartoon model for the mechanism of chromatin condensation and decondensation. Models for condensation and decondensation of chromatin, a determinant of transcriptional activity, involves enzymes for histone acetylation (HAT) and histone deacetylase (HDAC), DNA methylation, and methylation of histone H3K9 [47]. Cartoon representations are a typical means for scientific discourse for molecular biologists.Back to article page
